Hi,
I have a question regarding disk preparation. I have 4 nodes, each has 24 SSD, i would like to know whats the best practice to setup the disks. The pool will be used as a vmware datastore. im planning on using each disk as a brick without lvm, pool will be distributed replicas with sharding enabled, do you have any comments on this setup ? because i dont know if i should use all disks as one big disk with RAID and disable sharding, or use each disk as a brick with sharding enabled.
also, Redhat website stated that i have to use LVM, but i couldn't get an answer on why i should use LVM or why i should't. "You should not create Red Hat Storage volume bricks using raw disks. Bricks must be created on thin-provisioned Logical Volumes (LVs)" https://access.redhat.com/articles/1273933
Thank you. --
